I have a token slipping through that should have be rewritten.
In the following input:
version 2.0.0
.data
.end
code main
putr1 main.1
forkep r1
stop
Translates to:
-1 "2.0.0" ; version 2.0.0
-5 ; .data
code -2 1024 ; code 1024
178 1036 ; putr1 1036
61 0 1 ; forkep 0 1
62 0 ; stop
The word code at the beginning of line 3 shouldn't be there.
Considering it was rewritten like this and CODE is an imaginary token:
codeBlock
: 'code' a=codeLabel {
if (labels.get($a.text) == null)
labels.put($a.text, new Integer(address));
} EOL codeEl -> ^(CODE codeLabel codeEl)
;
codeLabel
: ID
;
